Maybe next week.</p> <p>Your audio bandpass filter brings back horrible memories of a piece of test equipment we made for BT along while ago. It had a 2kHz 20Hz wide bandpass filter implemeneted by a cascade of 8th order elipptical high pass and low pas filters. Each filter used two quad op amps arranged as pot tuneable gyrator&quot;LC&quot; stages. 16 adjustments in all. When you got good at it you could tune one in under an hour ! But no fancy tools, just sig gen, True RMS meter with digitial read out (Fluke 8050 I think). I might well have traded a leg for an MXO4 at that time.</p> <p></p> <p>MK</p><img src="https://community.element14.com/aggbug?PostID=26693&AppID=13&AppType=Weblog&ContentType=0" width="1" height="1">RE: MXO 4 New Feature: Log Frequency Axis Spectrum Analysis!https://community.element14.com/technologies/test-and-measurement/b/blog/posts/mxo-4-new-feature-log-frequency-axis-spectrum-analysisSat, 12 Aug 2023 00:37:04 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:6d356879-ce17-4d49-ba72-86c19b4ac029baldengineer1<p>Thanks for showing it off! I saw it in the release notes, but it&#39;s going to be a few weeks before I can update my firmware.</p> <p>I&#39;m so glad they added it.</p><img src="https://community.element14.com/aggbug?PostID=26693&AppID=13&AppType=Weblog&ContentType=0" width="1" height="1">
